, To all whom t mayoria-cem: Be itknown that 1,GEoRGE CRossLAND, a

fcitizen, of the United States, rresiding at `l lAmsterdam, county of'vMontgomery, State- '5i ofNewI York, have inventedcertainnewand c useful Improvements rin 'v f Reeds, of`

amovedsubstantially to the very tops ofthe which the following isaspecification; i

The present invention relates toreeds and more particularly to reeds'for'fpilefabric Y from the description taken in connection `l from jumping? out ofthe spacesfor slots between adjacent dents.'l This wire' issupported by two spaced posts vsecured to the base ofthefreed. Thearra-ngement is "such ``that'the wire plevents the "warp"threadsl` 2o ifrommoving into the topmost portion of said slotsj or spaces, with the resultthat the warpthreads or ground"fabric` isf some dls- `tance from the'top of thereed even when said threads occupyythe highest positions they `can assume. The knifethat cuts f the tuftstravel' in a plane inclined slightlyto` fthe horizontal y and substanti'ally tangent to the ytop of the ree`d.By reason of the -fact that ,the warp threads, even in the7 highest 30,l position, are removed considerably from the topfof the reed, theknife cannotrut the `-tufts very@y close tothe'warpqthreads .or Vgroundfabric:I H

It is one ofthe principal aims of the priessor that the knife" can cut the `tufts much closer to the ground fabricthan heretofore.

Other objects of the invention rare to pro# yvide an improved form of dent andino-i 4o proved n'leans for supportinglthe retaining wire.

Tothesecnds, the ,dents ci `*the present in- 1 `vention comprise single straight bars shaped at their lower ends to htin recessesiuthe i base of the reed and "ati their upperf'ends so thatthe slots or spacesbetween'adjacent dents will be restricted to prevent lateral ydisplacement (of the warp threads 'when they' occupy these u spaces. Intermediate itsend portions each dent isrounded 1n cross section Vso thatV no 'sharpyedges are presented tov cut or Vinjure the warp 'threadskr in their ver- L ent invention toprovideI a reed constructedfv ears areso located, that the lpath of the cutting .knife is much w closer to the warp threads, when .in their 'highesty positions, than heretofore. Furthermore, the wire iS supported so that the warpthreadsinay be slots or spaces between adjacent dents.

.These and other objects will beapparent v'with the drawings in whichy Figure 1., is a front elevation of a portion of' the reed constructed in accordance with thev present Vinvention )A uigure 2 is a. vertical sectional elevation ofthe reed,V

'e Flgure 6 is a fragmentary horizontal sectional View taken substantiallj7 on the liuc 6-6 of Figure 2.

Referring to thedraivings, it willl be seen that the form of reed illustrated comprises a rack or base iba-r "11,' dents 10: and a retaining wire 18.

The dents l() are rigidly secured in spaced slots inthe rack or base bar 1l in any suitable manner, ask bylsoldering. Each dent consists of aI Vsingle straight bar, the middle vport-ion being rounded as viewed in'cross sectionisee Fig. Vetiandits end portions being substantially rectangular.. Asshown inFigure 5, the lower end portion is rcctan gular or otherwise shaped to snugly iii'. the slots in therack or base bar 1,1. The upper end porton is substantially rectangular eX- cept that the bar is widened in any suitable manner in order to further restrict the space between the adjacent dents. In the forni of the invention shown, this is accomplished by slitting vertically the frontr of the upper end of the dent as shown atlt in Figure 3. It is to be'unders'tood, however, that the result might be accomplished in other ways.

This construction of reeds lends itself to accurate quantity production. Furthermore, the warpthreads may be crossed to form the shed without injuring or breaking tures 17 for the retaining wire 18. It will be noted thatv the retaining wire 18 is supported so that 'the warp threads may approach nearer :to the top of the reed than heretofore. Furthermore, the upper front corner 18a of each dent is at a lower elevation thanthe :top of the ea-r. As la. result, the path 19 of the knife, at the front of the reed, is closer to the warp threads ythan with prior constructions. In this structure a plane tangent to the top of the ear and the upper front corner of the dent is inclined forwardly. Furthermore, a plane tangent to the :top of the retaining wire 18 and the front corner of the dent is substantially hori zontal. Expressed in still another way, the l`vertical `distance between a horizontal plane tangent to the under Aside -of the retaining wire 118, on the one hand, and a horizontal plane tangent to the upper front corner of a' dent is less than heretofore.

lith this form and arrangement-of parts it is `clearthat the warp threads can be raised to a plane much nearer to the path of the -knife than heretofore, with the result that the pile .may be cut closer to the ground fabric, and moreover this result has been secured without decreasing the vertical travel of the warp threads. .in the present invention, haw'e a 'maximum vertical travel while still "retained in the reed.

Although the invention has been described in detail, it is to be understood that it is'not thus limited but includes `modifications .and `changes which come `within the scope of the appended claims. i

Having thus rdescribed my invention, what is claimed Vas new and desired to be `secured by U. S. Letters Patent is: y

1. A reed for pile fabric looms, including in combination, `a plurality of dents, at least two of said dents each having an ear atthe yupper rear `corner thereof and means carried by said ears for retaining warp threads in the reed.

9.. reed for pile fabric looms, including in combination, a plurality ofdentS, kat least two of said dents having a rearwardly eX- tending ear at the upper rear corner thereof, the 'top surfaces `of said years being disposed above the upper front corner of said dent, and :means carried yby said ears for retaining warp threads in the reed,

Indeed these threads,

4. A reed for pile fabric looms, including in combination, a plurality of dents, the Vupper front portion of each dent-being widened laterally, thereby vconstricting the spaces be- `tween adjacent dents, lat least two of said dents each having an ear at the upper rear corner thereof, and means carried by said ears for retaining warp threads in the reed, a plane tangent to the top of said `means and the front corners of the dents Ybeing substantially horizontal.

v6. A reed for pile fabric looms, including in combination, a plurality of dents, a slotted rack for supporting said dents, each dent at its lower end having a rectangular portion adapted to fit into the slots of said rack and at its upper end asubstantially Vrectangular portion widened laterally at its front face., whereby the space between adjacent dent-s is wider at the lower than the upper ends of thefdents.

7. A reed4 for pile fabric looms, including in combination, a. -plurality of dents, a lslotted rack for supporting and spacing the lower ends of said dents, .each dent consistmg of a single straight bar of solid cross section, its lower end portion being of rectangular cross section andadapted to titinto the slots` of said rack, its upper end portion being of -substantially rect-angular cross section and widened laterally for const-rioting the space between the upper ends of adjacent dents, -theportion of the dent intermediate said end portions having a rounded outline as viewed in cross section, an apertured ear at the rear upper corner of each dent, and a wire passing through said cars and ,extending across the back of said reed for preventing warp threads from rising above the upper ends of said dents. 'l

8. A reed for pile fabric looms,`incl1uling in combination, a plurality o-f dents, a slotted rack for supporting and spacing the lower ends of said dents, each dent consisting of a single straight bar of solid cross section, its lower end portion being yshaped to fit into lthe slots of -said rack, and its upper end portion being formed to provide a restricted space between adjacent dents, an

apertured earl at the upper rear corner of Vsaid dents, and a Wire supported in the apertures of said ears and extending across the back of the reed, forpreventing the Warp threads from rising above Ythe upper ends of saiddents.

9. l.As an varticle of manufacture, a dent for pile fabric looms, consisting of a sin-V gle straight bar of solid cross section hav- 50 ing `its lower end portion of rectangular said end portions having a rounded outline as viewed in cross section, and an apertured ear at the rear upper corner 0f said dent.

In testimony whereof I hereunto affix my signature.,
